Lunase moon phase watch mechanism

Is this innovative for watch complications? It feels like it. It might be the first innovation for a while.

Consumes a lot of space under the dial, so occludes other complications.

Does the "double bosom" occlusion mechanism have a proper name? I always thought it was a bit daft — excusable on watches perhaps — but on larger clocks where there's plenty of space why not just have a half black sphere that rotates once per lunar month? (Even better would be a small model of the moon with a half black shade rotating around it).

Anyway: I made a (web) clock with that shows the moon position and phase: https://sunclock.net

I expected to see mention of the volvelle - a medieval device made of paper that could approximate the phase of the moon by moving a circular hole around a carefully designed track. There’s a long explanation of it at https://astrolabeproject.com/downloads/volvelle/deconstructi...

It takes a special kind of mind to tackle an idea so entrenched, rethink the design from first principles, do it well, and come up with something so different from what was there before.

Bravo.

Nice!

Ages ago, a "Moonphase" font which I did was used in the typesetting of _Calendrical Tabulations_, so this sort of thing has always been near to my heart (I also used to use a "Phases of the Moon" application as a desktop background).

Just use a digital screen for that part
